* New types for felica poller * New functions for felica data transmissions * Felica memory map extended with new fields * Init/deinit of mbedtls context added for felica encryption * Functions for session key and mac calculations added * Raw felica_poller implementation added * Removed MAC type parameter from check_mac function * Replaced all data fields needed for auth with context structure * Clean up felica_poller.c * Now RC block is filled with random numbers * New parameter for counting well-read blocks * Some cleanups * Felica file save and load logic added * Now we use card key from context for session key calculation * Copying card key to card block from auth context when both authentications succeeded, otherwise decrement blocks count by 1 * New felica poller event added * Moved some data structions to public namespace * FelicaAuthenticationContext struct moved to felica.h * Field type and name changed for better ones * Helper functions for felica_auth added to the app * New scene for felica card key input added * Logic for felica key input added * Auth context request processing added * Added block index definitions and replaced all index numbers with them * More macro defines * Replace nesting with do while block * New function for write operations mac calculation added * Replace nesting with do while block * Make functions static for now because they are used internally * Wrote some comments * Raw felica render implementation * New felica scenes * Adjusted felica dump rendering according design requirements * New felica scene added * Helper for switching scene during unlock added * Added warning scene and transfer to it * Moved unlock scene logic to separate files * Magic number changed * New felica render logic * Felica scenes adjusted according to design requirements * Felica poller cleanups * Some asserts added and some fixed * Replcaed asserts to checks in public api * Fixed pvs warnings in felica_poller * New event for felica_poller added for incomplete read actions * Handling of new poller event added * Update SConscript with felica files * Update api_symbols.csv with felica functions * Sync API versions Co-authored-by: あく <alleteam@gmail.com>
